Hi! Now I am modelling a building equipped with VRF system. Even though generally supply air temperature of Japanese VRF is higher by 10 degrees Celcius than zone setpoint temperature, the model now i am modelling supplies in approximately 41 degrees Celcius. so i want to fix the VRF supply air temperature as 32 degrees celcius. how can i do this?

i've already tried SetpointManager:FollowSystemNodeTemperature. but it didn't work. additionally, SetpointManager:Warmest and SetpointManager:WarmestTemperatureFlow don't work for VRF systems
